The Oceanweather Inc. (OWI) forecast group is now running an Arctic wave model domain covering 50N up to the North Pole, with a grid resolution of roughly 18 km. The model implements the parametric ice physics in WavewatchIII (WW3) using continuous and time-varying ice concentration inputs from the European Center for Medium Range Forecasting (ECMWF) forecast cycle. The wave model runs to a forecast horizon of 7 days, and outputs include fields of up to three wave trains. Full spectra points are available in addition to standard bulk wave parameters.
